Polar Organic Chemical Integrative Samplers Development : An approach to solute transfer rate mechanism

Accurate assessments of contaminant concentrations based on traditional grab sampling methods are not always possible. Very large sample volumes are required to accurately sample contaminants at low levels and there is often low recovery of polar compounds in liquid to liquid extraction techniques. There are various types of samplers with different design characteristics proposed for the sampling of aquatic pollutants of different polarities. Polar organic chemical integrative samplers (POCISs) have been designed to sequester and concentrate polar organic chemicals. The POCISs enable the estimation of the cumulative aqueous exposure to bioavailable hydrophilic organic chemicals and permit the estimation/determination of the biologically relevant time-weighted average (TWA) concentrations. This book is unique in bringing together guidance for postgraduate students and young researchers to work on development of Passive Sampling Techniques and thier accuracy in Environmental Monitoring. The perfornace of solute transfer rate and the strengths and weaknesses of applicability of this technology are considered.
